Abstract:
The combustion behavior of anthracite, biomass (Ficus virens) char and their blends were investigated by thermogravimetry analysis (TGA). The combustion process mainly focused on the volatile combustion and char combustion. The addition of char reduced the initial temperature and final temperature of fuels. The interactions firstly inhibited and then facilitated. When the blending ratio was 70AN30FV, the antagonism was the minimum, and synergism was the strongest at 830 K for the random ratio. The kinetic models of Coats-Redfern (CR), Doyle equation (Doyle), Friedman (FR), Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (FWO) and distributed activation energy model (DAEM) were used to calculate the kinetic parameters. The average values of activation energy for CR and Doyle were close and that of KAS, FWO and DAEM were near. Based on these six models, the corresponding expectation equations of activation energy and pre-exponential factor were proposed and the best predicted results was CR model for 60AN40FV.
